以下進一步詳細說明本發明。
(A)有機聚矽氧烷
(A)成分為下述一般式(1)所表示的有機聚矽氧烷。
式(1)中,Ar所表示的芳香族基,可列舉苯基、聯苯基、萘基等的芳香族烴基,以及呋喃基等的含有雜原子(O、S、N)的芳香族基,此外,該芳香族基亦可具有鹵素原子(例如氯原子、溴原子、氟原子)等的取代基。Ar宜為非取代之芳香族烴基,特佳為苯基。
式(1)中的n為1≦n≦100,宜為1≦n≦50,較佳為1≦n≦20。若n小於1,則容易揮發,若n大於100,則組成物的黏度變高,使用性不良。
F1及F2互相獨立地為選自下述式(2)或下述式(3)所表示的基之基。
式(2)中,R1互相獨立地為碳原子數1~20的一價烴基。

上述一般式(1)所表示的有機聚矽氧烷可藉由例如以下的方法來合成。
藉由使有機聚矽氧烷(8)與有機聚矽氧烷(9)在鉑觸媒的存在下發生氫矽烷化反應而獲得。藉由將相對於1莫耳有機聚矽氧烷(8)的有機聚矽氧烷(9)莫耳數調整至0.4莫耳~2莫耳,可控制具有上述式(3)所表示的紫外線反應基的末端基之數相對於F1及F2所表示的全部末端基的合計數的比例。

況,深部硬化性會惡化。

聚矽氧組成物的調製方法
本發明之紫外線硬化性聚矽氧組成物,可藉由將上述(A)成分、(B)成分及因應必要(C)成分、(D)成分、其他成分攪拌及混合等而獲得。攪拌等的操作所使用的裝置不受特別限定,可使用擂潰機、三輥機、球磨機、行星式攪拌機等。另外還可將這些裝置適當地組合。
從本發明之紫外線硬化性聚矽氧組成物的黏度係以使用性的觀點看來,以5,000mPa.s以下為佳,3,000mPa.s以下為較佳。此外,黏度是使用旋轉黏度計,在25℃下測得之值。

秒鐘左右即可。
此外,在使用以往的氫矽烷化反應的組成物的情況,為了硬化,需要至少數小時左右的加熱步驟,而本發明之紫外線硬化性聚矽氧組成物能夠在非常短的時間硬化。

以下揭示調製例、實施例及比較例,對本發明作具體說明,然而本發明不受下述實施例限定。
此外,在下述例子中,組成物的黏度是使用旋轉黏度計,在25℃下測得之值。硬度、斷裂時的延伸度、拉伸強度是依據JIS-K6249作測定。此時的硬化條件,是使用EYE GRAPHICS股份有限公司製的燈管
H(M)06-L-61,在氮氣環境下進行2,000mJ/cm2的紫外線照射。另外,薄片的厚度定為2.0mm。
